• Jquery UI Datepicker not displaying

  - by scott

  UPDATE I have reverted back to Jquery 1.3.2 and everything is working, not sure what the problem is/was as I have not changed anything else apart of the jquery and ui library versions. UPDATE END I having an issue with the JQuery UI datepicker. The datepicker is being attached to a class and that part is working but the datepicker is not being displayed. Here is the datepicker code I am using and the inline style that is being generated when I click in the input box that has the class ".datepicker". $('.datepicker').datepicker({dateFormat:'dd/mm/yy'}); display:none; left:418px; position:absolute; top:296px; z-index:1; If I change the display:none to display:block the datepicker works fine except it dosen't close when I select a date. Jquery libraries in use: jQuery JavaScript Library v1.4.2 jQuery UI 1.8 jQuery UI Widget 1.8 jQuery UI Mouse 1.8 jQuery UI Position 1.8 jQuery UI Draggable 1.8 jQuery UI Droppable 1.8 jQuery UI Datepicker 1.8

• Speed vs security vs compatibility over methods to do string concatenation in Python

  - by Cawas

  Similar questions have been brought (good speed comparison there) on this same subject. Hopefully this question is different and updated to Python 2.6 and 3.0. So far I believe the faster and most compatible method (among different Python versions) is the plain simple + sign: text = "whatever" + " you " + SAY But I keep hearing and reading it's not secure and / or advisable. I'm not even sure how many methods are there to manipulate strings! I could count only about 4: There's interpolation and all its sub-options such as % and format and then there's the simple ones, join and +. Finally, the new approach to string formatting, which is with format, is certainly not good for backwards compatibility at same time making % not good for forward compatibility. But should it be used for every string manipulation, including every concatenation, whenever we restrict ourselves to 3.x only? Well, maybe this is more of a wiki than a question, but I do wish to have an answer on which is the proper usage of each string manipulation method. And which one could be generally used with each focus in mind (best all around for compatibility, for speed and for security). Thanks.

• Vista 64-bits development tools

  - by Workshop Alex

  Well, okay. There's Visual Studio 2008 and Embarcadero Delphi/Studio that are both able to create 64-bits .NET applications for Vista. And of course a lot of 32-bits applications will run on 64-bits Vista. If not, it's always possible to install VMWare to create a virtual 32-bits Windows XP system to run 32-bits applications. So, plenty of options. But what I would like to see is a list of true 64-bits applications for Windows Vista and better. So if you know any useful 64-bits product, please share! (Especially compilers that generate native 64-bits code.) Tools would basically be anything that would make development a bit easier. Thus, debugging tools, image processing tools to create icons and bitmaps, hex editors to check the contents of binary files, XML editors to change XML files, etc. The tools from SysInternals, for example, seem to provide 64-bits versions or even support 64-bits systems natively. But how about all those other editors, viewers, browsers and other tools that we developers like to use? A 64-bits version of the Norton Commander/Midnight Commander or other file managers would be nice too. And with compilers, how about COBOL/ForTran/ADA/SmallTalk/Lisp/Whatever compiler/languages for Vista? I would just like to see a complete list of anything useful for 64-bits development.

• Moq a function with 5+ parameters and access invocation arguments.

  - by beerncircus

  I have a function I want to Moq. The problem is that it takes 5 parameters. The framework only contains Action<T1,T2,T3,T4> and Moq's generic CallBack() only overloads Action and the four generic versions. Is there an elegant workaround for this? This is what I want to do: public class Filter : IFilter { public int Filter(int i1, int i2, int i3, int i4, int i5){return 0;} } //Moq code: var mocker = new Mock<IFilter>(); mocker.Setup(x => x.Filter( It.IsAny<int>(), It.IsAny<int>(), It.IsAny<int>(), It.IsAny<int>(), It.IsAny<int>(), It.IsAny<int>()) .Callback ( (int i1, int i2, int i3, int i4, int i5) => i1 * 2 ); Moq doesn't allow this because there is no generic Action that takes 5+ parameters. I've resorted to making my own stub. Obviously, it would be better to use Moq with all of its verifications, etc.

• What makes merging in DVCS easy?

  - by afriza

  I read at Joel on Software: With distributed version control, the distributed part is actually not the most interesting part. The interesting part is that these systems think in terms of changes, not in terms of versions. and at HgInit: When we have to merge, Subversion tries to look at both revisions—my modified code, and your modified code—and it tries to guess how to smash them together in one big unholy mess. It usually fails, producing pages and pages of “merge conflicts” that aren’t really conflicts, simply places where Subversion failed to figure out what we did. By contrast, while we were working separately in Mercurial, Mercurial was busy keeping a series of changesets. And so, when we want to merge our code together, Mercurial actually has a whole lot more information: it knows what each of us changed and can reapply those changes, rather than just looking at the final product and trying to guess how to put it together. By looking at the SVN's repository folder, I have the impression that Subversion is maintaining each revisions as changeset. And from what I know, Hg is using both changeset and snapshot while Git is purely using snapshot to store the data. If my assumption is correct, then there must be other ways that make merging in DVCS easy. What are those?

• mysql prevent displaying a row ONE which has reference in another row TWO but no reference in row THREE

  - by Jayapal Chandran

  I have a table like the following id | name | pid 1 | sam | NULL 2 | sams ref | 1 3 | pam | NULL For the first time the first row gets inserted which will have pid as null I insert a row which is related to the first row and then i insert a row which is new and which may be referred by another row in future. now i want only the third row to be displayed and not the first and second row as the second row contains the reference of first row. so if any row has a reference to another row then both the rows should not be displayed. Only rows which is not having any reference should be displayed. BESIDES, IS IT A GOOD PRACTICE? PLEASE ADVICE ON THIS. Edited When i updated in server the query is always giving empty result. here is what i have and this one When pid is NULL then that row should appear but when another entry in the same table with pid as its parent id or any other rows id appears then both the rows should not appear. so if any pid has been referred then both the rows should not appear. here only one row will refer another row and not more than that. in my localhost i have mysql version 5.0.1 or something like that but when i installed xampp in another system it had 5.5 and in the live server it was 5.3 so in version around 5.0 the query is returning rows but in higher versions it is returning empty rows. so now i this case how to make a query?

• Photoshop CS5 not recognising activeDocument

  - by Max Kielland

  I wrote a quite big script for Photoshop CS5.1 on my 64bit Vista machine. Now when I run the very same script on my new 64bit Windows 7 machine, Adobe ExtendScript Tool complains about activeDocument (no such element) in this simple script: #target photoshop var pDoc = app.activeDocument; alert("Done!"); I have tried both and without #target and choosing the target in the ExtendedScript Tool. Is there something I have missed, or do I need to install something more. I only installed the 64bit version of Photoshop. Is it so that the 32bit Photoshop has the script extensions? I don't see why I need to install both 32bit and 64bit versions if I'm only going to use the 64bit version. EDIT I installed the 32bit version as well. Tried the same script against 32 and 64 bit, still no difference. SOLVED The mystery is solved. It is embarrassing simple if you interpret the error message more careful. Of course I can't get an activeDocument if there are no documents in Photoshop, duh!?! I interpreted it as the statement activeDocument wasn't recognised, but of course if I have no document there is no such element (as a photoshop document) to give me. I'm used to C++ and would expect the reuslt to be a NULL value or similar if there is a problem to get the document... excuses, excuses ;) Well, if someone else should get into the same problem, here is the answer on my expense :D

• Range-based `for` statement definition redundancy

  - by GMan - Save the Unicorns

  Looking at n3092, in §6.5.4 we find the equivalency for a range-based for loop. It then goes on to say what __begin and __end are equal to. It differentiates between arrays and other types, and I find this redundant (aka, confusing). It says for arrays types that __begin and __end are what you expect: a pointer to the first and a pointer to one-past the end. Then for other types, __begin and __end are equal to begin(__range) and end(__range), with ADL. Namespace std is associated, in order to find the std::begin and std::end defined in <iterator>, §24.6.5. However, if we look at the definition of std::begin and std::end, they are both defined for arrays as well as container types. And the array versions do exactly the same as above: pointer to the first, pointer to one-past the end. Why is there a need to differentiate arrays from other types, when the definition given for other types would work just as well, finding std::begin and std::end? Some abridged quotes for convenience: §24.6.5 The range-based for statement — if _RangeT is an array type, begin-expr and end-expr are __range and __range + __bound, respectively, where __bound is the array bound. If _RangeT is an array of unknown size or an array of incomplete type, the program is ill-formed. — otherwise, begin-expr and end-expr are begin(_range) and end(_range), respectively, where begin and end are looked up with argument-dependent lookup (3.4.2). For the purposes of this name lookup, namespace std is an associated namespace. and §24.6.5 range access template T* begin(T (&array)[N]); Returns: array. template T* end(T (&array)[N]); Returns: array + N.

• How to I display results of phpcs in VIM?

  - by Matt

  I am presently trying to use PHP Codesniffer (PEAR) in vim for PHP Files. I have found 2 sites that give code to add into the $HOME/.vim/plugin/phpcs.vim file. I have added the code and I "think" it is working, but I cannot see the results, I only see one line at the very bottom of vim that says (1 of 32) but I cannot see any of the 32 errors.

• How to write to a varchar(max) column using ODBC

  - by andyjohnson

  Summary: I'm trying to write a text string to a column of type varchar(max) using ODBC and SQL Server 2005. It fails if the length of the string is greater than 8000. Help! I have some C++ code that uses ODBC (SQL Native Client) to write a text string to a table. If I change the column from, say, varchar(100) to varchar(max) and try to write a string with length greater than 8000, the write fails with the following error [Microsoft][ODBC SQL Server Driver]String data, right truncation So, can anyone advise me on if this can be done, and how? Some example (not production) code that shows what I'm trying to do: SQLHENV hEnv = NULL; SQLRETURN iError = SQLAllocEnv(&hEnv); HDBC hDbc = NULL; SQLAllocConnect(hEnv, &hDbc); const char* pszConnStr = "Driver={SQL Server};Server=127.0.0.1;Database=MyTestDB"; UCHAR szConnectOut[SQL_MAX_MESSAGE_LENGTH]; SWORD iConnectOutLen = 0; iError = SQLDriverConnect(hDbc, NULL, (unsigned char*)pszConnStr, SQL_NTS, szConnectOut, (SQL_MAX_MESSAGE_LENGTH-1), &iConnectOutLen, SQL_DRIVER_COMPLETE); HSTMT hStmt = NULL; iError = SQLAllocStmt(hDbc, &hStmt); const char* pszSQL = "INSERT INTO MyTestTable (LongStr) VALUES (?)"; iError = SQLPrepare(hStmt, (SQLCHAR*)pszSQL, SQL_NTS); char* pszBigString = AllocBigString(8001); iError = SQLSetParam(hStmt, 1, SQL_C_CHAR, SQL_VARCHAR, 0, 0, (SQLPOINTER)pszBigString, NULL); iError = SQLExecute(hStmt); // Returns SQL_ERROR if pszBigString len > 8000 The table MyTestTable contains a single colum defined as varchar(max). The function AllocBigString (not shown) creates a string of arbitrary length. I understand that previous versions of SQL Server had an 8000 character limit to varchars, but not why is this happening in SQL 2005? Thanks, Andy

• Tips on managing dependencies for a release?

  - by Andrew Murray

  Our system comprises many .NET websites, class libraries, and a MSSQL database. We use SVN for source control and TeamCity to automatically build to a Test server. Our team is normally working on 4 or 5 projects at a time. We try to lump many changes into a largish rollout every 2-4 weeks. My problem is with keeping track of all the dependencies for a rollout. Example: Website A cannot go live until we've rolled out Branch X of Class library B, built in turn against the Trunk of Class library C, which needs Config Updates Y and Z and Database Update D, which needs Migration Script E... It gets even more complex - like making sure each developer's project is actually compatible with the others and are building against the same versions. Yes, this is a management issue as much as a technical issue. Currently our non-optimal solution is: a whiteboard listing features that haven't gone live yet relying on our memory and intuition when planning the rollout, until we're pretty sure we've thought of everything... a dry-run on our Staging environment. It's a good indication but we're often not sure if Staging is 100% in sync with Live - part of the problem I'm hoping to solve. some amount of winging it on rollout day. So far so good, minus a few close calls. But as our system grows, I'd like a more scientific release management system allowing for more flexibility, like being able to roll out a single change or bugfix on it's own, safe in the knowledge that it won't break anything else. I'm guessing the best solution involves some sort of version numbering system, and perhaps using a project management tool. We're a start-up, so we're not too hot on religiously sticking to rigid processes, but we're happy to start, providing it doesn't add more overhead than it's worth. I'd love to hear advice from other teams who have solved this problem.

• I'v installed NetBeans 6.8 on my MacOS X MacBook and the logs say it cannot be run, any ideas?

  - by codezealot

  I've installed NetBeans 6.8 on my MacBook, and the installation results indicated success. However, every single time I attempt to run the application is shuts down. I monitored the process and noticed the following entries in the console that imply the application cannot be found? 3/19/10 10:20:20 PM [0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168] /Applications/NetBeans/NetBeans 6.8.app/Contents/MacOS/netbeans: line 57: dirname: command not found 3/19/10 10:20:20 PM [0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168] Cannot read cluster file: /../etc/netbeans.clusters 3/19/10 10:20:20 PM com.apple.launchd.peruser.501[77] ([0x0-0x22022].org.netbeans.ide.baseide.200912041610[22168]) Exited with exit code: 1 I started researching how to set the default JDK for use by NetBeans, and found repeated use of the following command line entry; netbeans --jdkhome /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home -- from http://wiki.netbeans.org/JDKVersionAndMacOS When I attempt the command line above, I receive "netbeans command not found". So do I ... 1.) Need to create a command called "netbeans" that points to my install location for NetBeans 6.8? If so how do I do that? 2.) How do I get to the netbeans.conf file for NetBeans 6.8, does one even exist for it? It gets even more interesting, the above happens with Eclipse as well. Yippie.

• Using a version control system as a data backend

  - by JacobM

  I'm involved in a project that, among other things, involves storing edits and changes to a large hierarchical document (HTML-formatted text). We want to include versioning of textual changes and of structural changes. Currently we're maintaining the tree of document sections in a relational database, but as we start working on how to manage versioning of structural changes, it's clear that we're in danger of having to write a lot of the functionality that a version control system provides. We don't want to reinvent the wheel. Is it possible that we could use an existing version control system as the data store, at least for the document itself? Presumably we could do so by writing out new versions to the filesystem, and keeping that directory under version control (and programmatically doing commits and so forth) but it would be better if we could directly interact with the repository via code. The VCS that we are most familiar with is Subversion, but I'm not thrilled with how Subversion represents changes to the directory structure -- it would be nice if we could see that a particular revision included moving a section from Chapter 2 to Chapter 6, rather than just seeing a new version of the tree. This sounds more like the way a system like Mercurial handles changes to the structure. Any advice? Do VCS's have public APIs and so forth? The project is in Java (with Spring) if it matters.

• url rewrite & redirect question

  - by Shawn

  Say currently I have url like : http://mydomain.com/showpost.php?p=123 Now I want to make it prettier : http://mydomain.com/123/post-title I'm using apache rewrite which grabs segment '123' and put the url back to http://mydomain.com/showpost.php?p=123 OK. Here is the problem. I want to redirect the original non-pretty urls which were indexed by Google to the pretty versions, I want this because I heard that Google may punish me if he sees multiple urls pointing to identical content. So I need to redirect /showpost.php?p=123 to /123/post-title This I have to do in my php code coz there's no way Apache to be able to figure out the 'post-title', but if I put the redirect code in php code, then it will be a infinite loop, such as : Request : /showpost.php?p=123 redirected to : /123/post-title rewritten to: /showpost.php?p=123 redirected again to : /123/post-title ... So on and so forth. Sorry I should Google the solution first but I really don't know how to describe my situation in English to make Google return reasonable results. Please help me. Thanks.

• Apache with JBOSS using AJP (mod_jk) giving spikes in thread count.

  - by Beginner

  We used Apache with JBOSS for hosting our Application, but we found some issues related to thread handling of mod_jk. Our website comes under low traffic websites and has maximum 200-300 concurrent users during our website's peak activity time. As the traffic grows (not in terms of concurrent users, but in terms of cumulative requests which came to our server), the server stopped serving requests for long, although it didn't crash but could not serve the request till 20 mins. The JBOSS server console showed that 350 thread were busy on both servers although there was enough free memory say, more than 1-1.5 GB (2 servers for JBOSS were used which were 64 bits, 4 GB RAM allocated for JBOSS) In order to check the problem we were using JBOSS and Apache Web Consoles, and we were seeing that the thread were showing in S state for as long as minutes although our pages take around 4-5 seconds to be served. We took the thread dump and found that the threads were mostly in WAITING state which means that they were waiting indefinitely. These threads were not of our Application Classes but of AJP 8009 port. Could somebody help me in this, as somebody else might also got this issue and solved it somehow. In case any more information is required then let me know. Also is mod_proxy better than using mod_jk, or there are some other problems with mod_proxy which can be fatal for me if I switch to mod__proxy? The versions I used are as follows: Apache 2.0.52 JBOSS: 4.2.2 MOD_JK: 1.2.20 JDK: 1.6 Operating System: RHEL 4 Thanks for the help.

• How to retrieve value from ViewData when the object is not a string?

  - by Richard77

  Hello, Here's the functionality I'd like to exploit: I've a class myClass and would like to iterate over a collection that contains all the properties of that class. I'd like to send the index of that collection along with the other data so that I can control the each sequence of the iteration. Here's simplified versions of a Action method and View (I'll use the same action-view for that functionality). 1) Action public ActionResult CreateHierarchy(int? index) { if(index < PropertiesOfMyClass.Lenght) { //Other code omitted ViewData["index"] = ((index == null) ? 1 : index++); Return View(); } } 2)View <% Using(Html.BeginForm()){%> //Other Code omitted <% = Html.Hidden("Index", ViewData["index"])%> <input type = "submit" value = "Do someting"/> <%}%> I've also placed this at the bottom of the page so that I can check the value of the index, <% = ViewData["index"]%> Unfortunately, its not working. I'm getting only the number 1. I'm missing something? such as a cast for the Viewdata? Should I write something like this: <% = Html.Hidden("index", (int)ViewData["index"])%> It's not working either Thanks for helping

• How to use the Request URL/URL Rewriting For Localization in ASP.NET - Using an HTTP Module or Globa

  - by LocalizedUrlDMan

  I wanted to see if there is a way to use the request URL/URL rewriting to set the language a page is rendered in by examining a portion of the URL in ASP.NET. We have a site that already works with ASP.NET’s resource localization and user’s can change the language that they see pages/resources on the site in, however the current mechanism in not very search engine friendly since the language variations for each language all appear as one page. It would be much better if we could have pages like www.site.com/en-mx/realfolder/realpage.aspx that allow linking to culture specific versions of a page. I know lots of people have likely done localization through URL structures before and I wanted to know if one of your could share how to do this in the Global.asax file or with an HTTP Module (pointing to links to blog postings would be great too). We have a restriction that the site is based on ASP.NET 2.0 (so we can't used the 3.5+ features yet). Here is the example scenario: A real page exits at: www.site.com/realfolder/realpage.aspx The page has a mechanism for the user to change the language it is displayed in via a dropdown. There are search engine optimization and user links sharing benefits to doing this since people can link directly to a page that has content that is applicable to a certain language (this could also include right-to-left layouts for languages like Japanese). I would like to use an HTTP module to see if the first part of the URL after www.site.com, site.com, subdomain.site.com, etc. contains a valid culture code (e.g. en-us, es-mx) then use that value to set the localization culture of the page/resources based on that URL. So if the user accesses the URL www.site.com/en-MX/realfolder/realpage.aspx Then the page will render in Mexico’s variant of Spanish. If the user goes to www.site.com/realfolder/realpage.aspx directly the page would just use their browser’s language settings.

• Mac OS X linker error in Qt; CoreGraphics & CGWindowListCreate

  - by Jake Petroules

  Here is my .mm file #include "windowmanagerutils.h" #ifdef Q_OS_MAC #import </System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Headers/CGWindow.h> QRect WindowManagerUtils::getWindowRect(WId windowId) { CFArrayRef windows = CGWindowListCreate(kCGWindowListOptionOnScreenOnly, kCGNullWindowID); return QRect(); } QRect WindowManagerUtils::getClientRect(WId windowId) { return QRect(); } QString WindowManagerUtils::getWindowText(WId windowId) { return QString(); } WId WindowManagerUtils::rootWindow() { QApplication::desktop()->winId(); } WId WindowManagerUtils::windowFromPoint(const QPoint &p, WId parent, bool(*filterFunction)(WId)) { return NULL; } void WindowManagerUtils::setTopMostCarbon(const QWidget *const window, bool topMost) { if (!window) { return; } // Find a Cocoa equivalent for this Carbon function // [DllImport("/System/Library/Frameworks/Carbon.framework/Versions/Current/Carbon")] // OSStatus ret = HIViewSetZOrder(this->winId(), kHIViewZOrderAbove, NULL); } #endif The linker is telling me "_CGWindowListCreate" is undefined. What libraries must I link to? Apple's documentation is not very helpful on telling what to include or link to, like MSDN is. Also I couldn't just do #import <CGWindow.h>, I had to specify the absolute path to it... any way around that?

• grep 5 seconds of input from the serial port inside a shell-script

  - by pica

  I've got a device that I'm operating next to my PC and as it runs it's spitting log lines out it's serial port. I have this wired to my PC and I can see the log lines fine if I'm using either minicom or something like: ttylog -b 115200 -d /dev/ttyS0 I want to write 5 seconds of the device serial output to a temp file (or assign it to a variable) and then later grep that file for keywords that will let me know how the device is operating. I've already tried redirecting the output to a file while running the command in the background, and then sleeping 5 seconds and killing the process, but the log lines never get written to my temp file. Example: touch tempFile ttylog -b 115200 -d /dev/ttyS0 >> tempFile & serialPID=$! sleep 5 #kill ${serialPID} #does not work, gets wrong PID killall ttylog cat tempFile The file gets created but never filled with any data. I can also replace the ttylog line with: ttylog -b 115200 -d /dev/ttyS0 |tee -a tempFile & In neither case do I ever see any log lines logged to stdout or the log file unless I have multiple versions of ttylog running by mistake (see commented out line, D'oh). I have no idea what's going on here. It seems to be a failure of redirection within my script. Am I on the right track? Is there a better way to sample 5 seconds of the serial port?

• JDBC/OSGi and how to dynamically load drivers without explicitly stating dependencies in the bundle?

  - by Chris

  Hi, This is a biggie. I have a well-structured yet monolithic code base that has a primitive modular architecture (all modules implement interfaces yet share the same classpath). I realize the folly of this approach and the problems it represents when I go to deploy on application servers that may have different conflicting versions of my library. I'm dependent on around 30 jars right now and am mid-way though bnding them up. Now some of my modules are easy to declare the versioned dependencies of, such as my networking components. They statically reference classes within the JRE and other BNDded libraries but my JDBC related components instantiate via Class.forName(...) and can use one of any number of drivers. I am breaking everything up into OSGi bundles by service area. My core classes/interfaces. Reporting related components. Database access related components (via JDBC). etc.... I wish for my code to be able to still be used without OSGi via single jar file with all my dependencies and without OSGi at all (via JARJAR) and also to be modular via the OSGi meta-data and granular bundles with dependency information. How do I configure my bundle and my code so that it can dynamically utilize any driver on the classpath and/or within the OSGi container environment (Felix/Equinox/etc.)? Is there a run-time method to detect if I am running in an OSGi container that is compatible across containers (Felix/Equinox/etc.) ? Do I need to use a different class loading mechanism if I am in a OSGi container? Am I required to import OSGi classes into my project to be able to load an at-bundle-time-unknown JDBC driver via my database module? I also have a second method of obtaining a driver (via JNDI, which is only really applicable when running in an app server), do I need to change my JNDI access code for OSGi-aware app servers?

• Problem with GWT behind a reverse proxy - either nginx or apache

  - by Don Branson

  I'm having this problem with GWT when it's behind a reverse proxy. The backend app is deployed within a context - let's call it /context. The GWT app works fine when I hit it directly: http://host:8080/context/ I can configure a reverse proxy in front it it. Here's my nginx example: upstream backend { server 127.0.0.1:8080; } ... location / { proxy_pass http://backend/context/; } But, when I run through the reverse proxy, GWT gets confused, saying: 2009-10-04 14:05:41.140:/:WARN: Login: ERROR: The serialization policy file '/C7F5ECA5E3C10B453290DE47D3BE0F0E.gwt.rpc' was not found; did you forget to include it in this deployment? 2009-10-04 14:05:41.140:/:WARN: Login: WARNING: Failed to get the SerializationPolicy 'C7F5ECA5E3C10B453290DE47D3BE0F0E' for module 'https://hostname:444/'; a legacy, 1.3.3 compatible, serialization policy will be used. You may experience SerializationExceptions as a result. 2009-10-04 14:05:41.292:/:WARN: StoryService: ERROR: The serialization policy file '/0445C2D48AEF2FB8CB70C4D4A7849D88.gwt.rpc' was not found; did you forget to include it in this deployment? 2009-10-04 14:05:41.292:/:WARN: StoryService: WARNING: Failed to get the SerializationPolicy '0445C2D48AEF2FB8CB70C4D4A7849D88' for module 'https://hostname:444/'; a legacy, 1.3.3 compatible, serialization policy will be used. You may experience SerializationExceptions as a result. In other words, GWT isn't getting the word that it needs to prepend /context/ hen look for C7F5ECA5E3C10B453290DE47D3BE0F0E.gwt.rpc, but only when the request comes throught proxy. A workaround is to add the context to the url for the web site: location /context/ { proxy_pass http://backend/context/; } but that means the context is now part of the url that the user sees, and that's ugly. Anybody know how to make GWT happy in this case? Software versions: GWT - 1.7.0 (same problem with 1.7.1) Jetty - 6.1.21 (but the same problem existed under tomcat) nginx - 0.7.62 (same problem under apache 2.x) I've looked at the traffic between the proxy and the backend using DonsProxy, but there's nothing noteworthy there.

• How to terminate all [grand]child processes using C# on WXP (and newer MSWindows)

  - by NVRAM

  Question: How can I determine all processes in the child's Process Tree to kill them? I have an application, written in C# that will: Get a set of data from the server, Spawn a 3rd party utility to process the data, then Return the results to the server. This is working fine. But since a run consumes a lot of CPU and may take as long as an hour, I want to add the ability to have my app terminate its child processes. Some issues that make the simple solutions I've found elsewhere are: My app's child process "A" (InstallAnywhere EXE I think) spawns the real processing app "B" (a java.exe), which in turns spawns more children "C1".."Cn" (most of which are also written in Java). There will likely be multiple copies of my application (and hence, multiple sets of its children) running on the same machine. The child process is not in my control so there might be some "D" processes in the future. My application must run on 32-bit and 64-bit versions of MSWindows. On the plus side there is no issue of data loss, a "clean" shutdown doesn't matter as long as the processes end fairly quickly.

• Retrieve a list of the most popular GET param variations for a given URL?

  - by jamtoday

  I'm working on building intelligence around link propagation, and because I need to deal with many short URL services where a reverse-lookup from an exact URL address is required, I need to be able to resolve multiple approximate versions of the same URL. An example would be a URL like http://www.example.com?ref=affil&hl=en&ct=0 Of course, changing GET params in certain circumstances can refer to a completely different page, especially if the GET params in question refer to a profile or content ID. But a quick parse of the page would quickly determine how similar the pages were to each other. Using a bit of machine learning, it could quickly become clear which GET params don't effect the content of the pages returned for a given site. I'm assuming a service to send a URL and get a list of very similar URLs could only be offered by the likes of Google or Yahoo (or Twitter), but they don't seem to offer this feature, and I haven't found any other services that do. If you know of any services that do cluster together groups of almost identical URLs in the aforementioned way, please let me know. My bounty is a hug.
